Marlin Jackson tore his ACL in practice on Wednesday and it will end his season.  Jackson played in 4 games for the Colts this season and he made 10 tackles, had 1 tackle for a loss, he defensed 1 pass and he had 1 interception.  This injury will hurt the depth of the Colts’ secondary but he wasn’t playing that well this season when he was healthy so the Colts won’t miss him too much.
